Re: Gmail specific
My theory is that the Celtic parts of the British Isles don't have such a variety of surnames and firstnames as the Sassenach bit. In addition to that, many Scots families persist in the practice of naming eldest son after the father. So you could have the same name as your father, grandfather and great grandfather. (This was common in England in the Middle Ages, and possibly after.)
Of course, this effect is slightly offset by the sheer number of English people.
Mumble, something something, collision space?
